Growth responses of oligotrophic bacteria to substrate concentrations have been investigated in comparison with those of heterotrophic bacteria. The results suggested that oligotrophs were the group which could grow and produce a perceptible turbidity in the media containing less than 10 mg peptone C/L of medium.Taxonomic studies indicated that the most abundant group in the oligotrophic bacterial flora was consistent with that in the heterotrophic bacterial flora at each sampling station. However, the relative proportion of pseudomonads in the oligotrophs was higher than that in the heterotrophs (at stations H-24, H-28, H-29, Ab-1, Ab-2, and O-4), while the relative proportion of Vibrio in the former was lower than that in the latter (at stations H-24, H-28, H-29, O-4, and O-9).

Recent surveys of the Caribbean spiny lobster (Panulirus argus) in the Florida Keys and the Dry Tortugas revealed the presence of necrotic carapace lesions, which are commonly associated with bacterial shell disease in other crustaceans. To determine the etiology of these lesions, we obtained bacterial samples from diseased and nondiseased lobsters. Bacteria from these samples were isolated and identified by 16S ribosomal RNA sequencing. At least 600 bases of the 16S rRNA gene were aligned with sequences from known strains of marine bacteria. The analysis showed that the majority of the strains isolated from diseased and nondiseased lobsters are within the Vibrionaceae, a common family of marine bacteria. The majority of isolates identified as Vibrio species are clustered in a monophyletic group that does not include any of the known Vibrio species. Genbank BLAST analysis also confirmed these isolates as Vibrio and confirmed that they are not closely related to any known Vibrio species. These results suggest that the normal flora of P. argus is unique. The association of these bacteria both with lesions and with nondiseased animals suggests that the natural flora is responsible for the lesions seen in P. argus.

The intestinal microbial flora has risen to be one of the important etiological factors in the development of diseases like colorectal cancer, obesity, diabetes, inflammatory bowel disease, anxiety and Parkinson's. The emergence of the association between bacterial flora and lungs led to the discovery of the gut–lung axis. Dysbiosis of several species of colonic bacteria such as Firmicutes and Bacteroidetes and transfer of these bacteria from gut to lungs via lymphatic and systemic circulation are associated with several respiratory diseases such as lung cancer, asthma, tuberculosis, cystic fibrosis, etc. Current therapies for dysbiosis include use of probiotics, prebiotics and synbiotics to restore the balance between various species of beneficial bacteria. Various approaches like nanotechnology and microencapsulation have been explored to increase the permeability and viability of probiotics in the body. The need of the day is comprehensive study of mechanisms behind dysbiosis, translocation of microbiota from gut to lung through various channels and new technology for evaluating treatment to correct this dysbiosis which in turn can be used to manage various respiratory diseases. Microfluidics and organ on chip model are emerging technologies that can satisfy these needs. This review gives an overview of colonic commensals in lung pathology and novel systems that help in alleviating symptoms of lung diseases. We have also hypothesized new models to help in understanding bacterial pathways involved in the gut–lung axis as well as act as a futuristic approach in finding treatment of respiratory diseases caused by dysbiosis.
